[@Jaded] A broom closet with a makeshift 'out of order' sign that's just some scribble on a piece of paper taped onto the door. If you open it the door just leads to nothing but open sky loony tunes style.

A little corner of the library that is beyond time and space where students go to cram four hours of study five minutes before a test; but you can't fall asleep there or else you disappear.

A kleptomaniac gnome that lives in the walls that steals the left shoe of every pair you own.

I can't post a CS right now, but I'll give you a general idea of the character I'm thinking up. I'm going to be doing a play on the 'invisible girl' trope. A meek, seemingly uninteresting young lady with severe social anxieties that prevent her from speaking up in most situations. As a result she tends to be overlooked by most of her peers.

When her abilities manifest they'll be focused around stealth.

EDIT: She's also super into Tabletop Roleplaying and has a Rogue OC which she projects herself onto. Also digs Space.
